Can I extend my 90-day Non-O visa while in Thailand?

@George’s *********************

this is slowly turning into a train wreck. NO, you can only extend the 90 days stay permit out of a Non-Imm-O visa, by applying for the "one year Extension of Stay based on retirement", if you can fulfill the financial requirements needed for this one-year extension. Which are either an income affidavit by your embassy over a monthly minimum of 65,000 THB, or by a deposit of a minimum of 800,000 THB in a Thai bank account in your sole name, along with a proof that the money has already seasoned in your Thai bank account for two months prior to the day of application to the extension. If you cannot match up with this, you HAVE TO LEAVE Thailand before the 90 days expire, or you will be in OVERSTAY . . . there is nothing such as a one year LTV, and you cannot apply for another 90-days Non-Imm-O visa inside Thailand. . . . . . EXCEPT: if you exit and re-enter visa-exempt and get stamped in for 60 days. Then, and only then, you can apply on Immigration for the "change of visa type" from the 60 days visa-exempt stamp to the initial 90-days Non-Imm-O retirement visa. But for this, some different requirements need to be fulfilled as well. These are the 800,000 THB deposit with a proof that the money came from abroad, a rental contract, a completed TM30 registration etc etc

No, you get a 12-month extension to your 90-day visa

@Stuart ********

I went to immigration for the same visa and was going to loose 2 weeks, that was yesterday in khonkean

So going back the day before my extension expires,
